Does the body of a person with renal failure show any abnormal signs?

The occurrence of renal failure indicates a significant decline in kidney function. In a healthy individual, normal kidney function allows for proper metabolism and maintenance of internal stability. The kidneys play a crucial role in the excretion of urine, removing harmful substances accumulated in the body. Renal failure does not occur spontaneously; rather, various detrimental behaviors can damage the kidneys, leading to impaired physiological function and impacting overall health.

Renal failure presents distinct symptoms, such as abnormal urination. The kidneys are vital for urine excretion, and normal urination is essential for health. Adequate daily water intake should result in urination four to six times during the day, with the excreted urine being clear, transparent, odorless, and generally free of foam, indicating normal kidney function. However, when renal failure strikes, metabolic abnormalities occur, resulting in the improper excretion of fluids. Common characteristics include oliguria or anuria, as well as the presence of hematuria, proteinuria, and dark, foul-smelling urine. These signs should raise concerns about renal failure and prompt early intervention.

What other symptoms are associated with renal failure?

1. Decreased appetite

Renal failure not only manifests in abnormal urine characteristics but also presents warning signs through specific digestive system symptoms. In a healthy individual, digestion is smooth, appetite is good, and normal stools are excreted. However, in advanced stages of renal failure, significant decline in kidney function leads to the conversion of urea to ammonia-like substances by intestinal urease. This results in increased production of ammonia-like substances in the body, leading to inflammation and, in severe cases, ulcers in the intestinal mucosa. Consequently, normal digestion is impaired, often resulting in bloating, indigestion, and decreased appetite. These symptoms, when present, should be considered in conjunction with other signals of kidney disease and distinguished from common digestive system disorders to facilitate targeted treatment and disease management.

2. Body swelling

Immediate treatment is essential upon the onset of renal failure, as the condition poses a continuous threat to the patient's life and health, often accompanied by the characteristic of swelling during the disease course. Under normal circumstances, efficient metabolism allows for the excretion of accumulated harmful substances through urination, and stable indicators are also contingent upon normal urination. However, in advanced renal failure, water retention leads to reduced urine output, even with increased fluid intake, resulting in decreased urine volume and frequency. This oliguria or anuria, in turn, leads to bodily swelling, often observed as edema in the eyelids and lower limbs, signaling the onset of renal failure.

As a serious threat to health, renal failure is related to dietary factors, environmental influences, medication effects, and uncontrolled kidney diseases. Understanding the underlying causes of renal failure, avoiding triggers, and proper body maintenance are essential for staying healthy and preventing renal failure.
